Modeling HFC Production and Its Impact on CFC Emissions
Author Information
Author(s): Stephen Bourguet, Megan Lickley
Primary Institution: Georgetown University
Hypothesis
What are the emissions of CFCs associated with HFC production?
Conclusion
The study suggests that unreported feedstock production in low- to middle-income countries may explain unexpected emissions of CFCs.
Supporting Evidence
- 90% of CFC-113 emissions from HFC-134a production are unreported.
- 65% of CFC-114 emissions are linked to HFC-134a production.
- 81% of CFC-115 emissions are from by-products of HFC-125 production.
Takeaway
This study looks at how making certain chemicals can accidentally release harmful gases that hurt the ozone layer. It shows that some countries might not be reporting how much they are making.
Methodology
The study uses a Bayesian framework to estimate emissions of CFCs during the production of HFCs.
Potential Biases
Potential underreporting of emissions and production in low- to middle-income countries.
Limitations
The study relies on assumptions about chemical conversion rates and lacks insight into industrial processes.
Statistical Information
Confidence Interval
82–94% for CFC-113 and 47–77% for CFC-114 emissions.
